I recently installed a gen 1 Rachio system and when switching over the wiring, I discovered that I had a Hunter Mini-Clik Rain sensor installed on my house. The sensor was hooked into my old Toro controller with a red wire and a white wire. I transferred the red and white wires to the yellow sensor ports on the Iro. After doing this, I pushed the top of the sensor to simulate rain occurring, and in the Rachio app, the device status shows “rain sensor deactivated.” Judging from the rain sensor manual, pushing the top of the sensor should activate the rain sensor, not deactivate it.
I tried flipping the red wires around in the yellow connectors, but was still receiving the same result. I then put the red wire in the first yellow connector and the white wire in the common connector. I tested this by turning on my first zone and pushing down the top of the rain sensor and this caused the zone to shut off immediately, which is what is supposed to happen. My concern is that in my device updates section, it shows the “rain sensor activated” message when I push the sensor and the zone shits off, but then it immediately says “device status power cycle.” This does not seem normal to me, but I can’t get the rain sensor to function properly any other way. Can you please assist on how I should be setting this up?
